Hybrid stent

Abstract

A stent comprises a plurality of segments, including at least one segment which is in the form of a coil and at least one segment which is in a form other than a coil and which is balloon expandable or self-expandable.

1 . A stent comprising a plurality of segments, including at least one segment which is in the form of a coil and at least one segment which is in a form other than a coil and which is balloon expandable or self-expandable.  
     
     
         2 . The stent of  claim 1  having a first end segment and a second end segment, wherein each of the first and second end segments is in a form other than a coil and is balloon expandable or self-expandable.  
     
     
         3 . The stent of  claim 2  comprising only one segment which is in the form of a coil and which connects the first and second end segments.  
     
     
         4 . The stent of  claim 3  wherein the first and second end segments are self-expandable.  
     
     
         5 . The stent of  claim 4  wherein the first and second end sections are each formed of a plurality of braided filaments.  
     
     
         6 . The stent of  claim 5  wherein the filaments are made of spring steel.  
     
     
         7 . The stent of  claim 3  wherein the first and second end segments are balloon expandable.  
     
     
         8 . The stent of  claim 7  wherein the first and second end segments are each in the form of a tube comprising a plurality of interconnected serpentine segments.  
     
     
         9 . The stent of  claim 1  wherein the segment which is in the form of a coil is made of spring steel.  
     
     
         10 . A stent comprising a coil segment and a tubular, non-coil segment.  
     
     
         11 . The stent of  claim 9  wherein the tubular, non-coil segment is balloon expandable.  
     
     
         12 . The stent of  claim 9  wherein the tubular, non-coil segment is self-expandable.  
     
     
         13 . The stent of  claim 9  having a first end and a second end, the first end being a tubular, non-coil segment and the second end being a tubular, non-coil segment.  
     
     
         14 . The stent of  claim 10  where the coil segment is made of spring steel.  
     
     
         15 . The stent of  claim 10  wherein the coil segment has an outer diameter of no more than 6 mm when deployed.  
     
     
         16 . The stent of  claim 15  having an outer diameter of no more than 6 mm when deployed.  
     
     
         17 . The stent of  claim 15  having a length of no more than 20 mm.  
     
     
         18 . A method of treating a bodily vessel comprising the steps of: 
 providing a catheter, the catheter including a stent, the stent having a coil segment and at least one non-coil segment;    delivering the stent to a desired location in the bodily vessel, deploying the coil segment and either allowing the non-coil segment to self-expand or balloon expanding the non-coil segment.    
     
     
         19 . The method of  claim 18  wherein the coil segment is deployed across an aneurysm.  
     
     
         20 . A method of manufacturing a stent comprising the steps of: 
 providing a coil segment and a non-coil segment;    attaching the coil segment to the non-coil segment.    
     
     
         21 . The method of  claim 20  wherein the coil segment is adhesively bonded to the non-coil segment.  
     
     
         22 . The method of  claim 20  wherein the coil segment is welded to the non-coil segment.
